As the start of the CGI-accurate Shockwave I'm working on, I gave his left hand a wrist, modded the shoulders so they aren't so trollish, and made room so his head could use the ball-joint it's mounted on. Simple enough.
It looks rough at the moment because I'm still in the process of adding lots of mods to this figure.
Intended- right hand sculpted into the canon, cannon flare-tips, runes and textured painting, plus NEW feet to match the CGI. This last part has been the most troublesome. What's shown here are unmodified legs. The ones I'm reworking are sitting on the workbench. He'll have ankles and positionable feet (with the third horn-spike) that can still transform.
Ugh.
It's Shockwave, though. For me, that's all the incentive I need.

UPDATE- 6/26

So, I'm at the point where showing some WIPs of the rest of the figure may be useful. I'm still planning on adding bulk to the feet and shoulders (maybe). Aside from the obvious, I also trimmed a bit of the bicep which allows for more arm movement, filled in the hollow sections of the blade, and filed the heel to match the level of the front foot.
The paint I'm planning will take longer than the entire build, so I have that to look forward to.

C/C welcome.

UPDATE 7/3

I redesigned the feet, added heel rails, modded the arms a bit more, then primed and undercoated it with a mix of dark beaten steel and Testors purple pearl. Paint details will begin tomorrow once the paint has had time to cure. I plan on going to town with the paint apps. He's a bit more purple now than in the movie, but that'll change. He looks a bit speckly due to the paints used for the base coat, but that's actually what I was going for. The texturixing effect will add to the final result.

Thanks guys!
I'll be working a bit more on the legs and feet this week, so hopefully some painting can be done shortly. I'm going to go ballistic on that end. Cybertronian glyphs and all (even though the ones pictured in the CGI's and game stills are all just in alphabetical order).

The background is indeed from the fan art section. I believe it's called "End of the World".

Wow that's great. What ball joint did you use to articulate his wrist is that gundam? Why didn't you switch his forearms to make him more G1 accurate??

The joint is from some ball joint packs I ordered from HLJ. They're standad ball and hinge joints that can be used for pretty much anything.
Also, the movie isn't G1 so Shockwave having his gun on his right arm doesn't bother me at all.

I started building the compartment for the new feet to be mounted in. They'll be on a ball joint, and also swing from front-facing to the side where they'll form the arm/gun supports in tank mode. It's ending up to be a bit more complicated than I thought it would be, but still coming along nicely.

I don't have the figure with me, but I'll do my best to describe.
-Pull the wrist pin, and take the arm apart.
-Drill out a small bit on each of the interior sides where the pin was.
-Use a squarish ball joint cup that has small posts on the side (very commonly used for Gundam wrist and neck joints). These posts will need to fit in where you drilled out the pin spots. You may have to shave a bit off the interior hinge piece to make the socket fit when the arm's assembled.
-Shave off some of the plastic behind the wrist and slope it up to match the forearm.
-Cut the hinge joint off of the hand, and drill a hole to insert a ball joint post.

This mod is kind of easy to see in the first B&W close-up of the left arm.

Coming soon... NEW FEET! The ones pictured were way too off in proportions, so I had to start over with them. So far, it's coming along nicely.
